若将10-羟基-5，10-二氢磷杂吖嗪-10-氧化物和氯化亚砜的作用产物直接在甲醇溶液中回流，也得到双熔点甲酯，它与单熔点次膦酸甲酯具有不同的晶相结构。

In order to improve the electrocatalytic activity of the anode in the Direct Methanol Feul Cell, three kinds of transition metal substituted phosphomolybdic acid modified platinum electrodes were prepared, and the electrochemical behavior in the sulphuric acid solution of transition metal substituted phosphomolybdic acid modified platinum electrodes and their electrocatalytic effects of methanol oxidation were studyed. The anti-poison effect to carbon monoxide of the prepared electrodes were studied by the carbon monoxide adsorbing.

The photoisomerization of transvitamin D3 to cisvitamin D3 was carried out with this heterogeneous photosensitizer in ethanol and toluene solutions.

利用此固相光敏剂分别在乙醇和甲苯溶液中敏化反式维生素D3。

Similar photolytic products including CP 11, CP 28, and CP 56 were found in ethanol.

在乙醇溶液中则发现有相当於甲醇溶媒滞留时间的CP 11、CP 28及CP 56光解产物生成。

The photophysical properties of the dyes in different solvents and solid matrices are researched.

研究了它们在溶液和固体基质中的光物理性质。

Now, a convenient, efficient pinacol coupling of aldehydes mediated by zinc in good yields has been carried out in ammonia water in the presence of a little crown ether. Adding a small amount of crown ether was highly effective to enhance the yields of pinacol from 63% to 84%.

本文报道一种简便、有效的水相呐偶合反应，它是在含有少量冠醚的稀氨水溶液中，使用锌粉促进醛基化合物进行水相呐偶合反应，其中加入少量的冠醚有助于提高反应的产率，呐醇产率由63%提高到84%。

With a small quantity of water a brownish yellow solution is formed, which, however, in a very short time becomes warm and the fluoride decomposes; platinic hydrate is precipitated, and free hydrofluoric acid remains in solution.

由于少量的水棕黄色的解决方案是一个形成，其中，然而，在很短的时间变得温暖和氟化物分解；铂水合物的沉淀和自由仍然氢氟酸溶液中。

It reports that L-ascorbic acid's polarographic oxidation wave in acid solution and its application.

报道了L-抗坏血酸在酸性溶液中的极谱氧化波及其应用。

In this paper, polarographic and voltammetric behaviours of reactive brilliant red K-2BP have been studied in detail.
